@connorbaker:matrix.orgconnor (he/him)I’ll get on a gist of a rewrite, as well as design tradeoffs in offering a wrapped cuda_nvcc, cudaStdenv, or changing the global stdenv when cudaSupport is enabled (to provide both LTO and to prevent any possibilities of linking against multiple copies of glibc/glibcxx)06:31:21

I am still doing this, among other things

@connorbaker:matrix.orgconnor (he/him)Anyone free to review https://github.com/NixOS/nixpkgs/pull/383214 and https://github.com/NixOS/nixpkgs/pull/383511?15:34:10
@ss:someonex.netSomeoneSerge (back on matrix)In my backlog but might take me until the end of the week. I wish I could switch earlier15:54:52
@hexa:lossy.networkhexawondering if anyone here cares about onnxruntime a bit17:52:35
@hexa:lossy.networkhexaenabling openvino support breaks the tests for some reason, since it cannot find libonnxruntime_providers_shared.so in $out/lib/17:52:55
@hexa:lossy.networkhexa * enabling openvino support breaks the tests for some reason, since it cannot find libonnxruntime_providers_shared.so in $out/lib/ 17:53:06
@hexa:lossy.networkhexa * enabling openvino support breaks the tests for some reason, since it cannot find libonnxruntime_providers_shared.so in $out/lib/ 17:53:11
@hexa:lossy.networkhexaso I added a condition to disable the tests with openvinoSupport17:53:39
@hexa:lossy.networkhexa
>>> rt.get_available_providers()
['OpenVINOExecutionProvider', 'CPUExecutionProvider']
17:53:42
@hexa:lossy.networkhexa* so I added a condition to disable the tests with openvinoSupport, which gets me to here:17:53:54
@hexa:lossy.networkhexanow I wonder if enabling openvino by default is a good idea, when it requires disabling the tests17:54:14
@hexa:lossy.networkhexathe alternative would be that I enabled openvino support just in the downstream package that wants it17:58:20

@connorbaker:matrix.orgconnor (he/him)I haven’t found a use for it yet for the stuff I’d work on if I had time, so my only interaction with the ONNX ecosystem has been packaging it with CUDA support, and that’s been horrible… so I’m not inclined to look into it beyond what I absolutely must19:38:57

@hexa:lossy.networkhexa SomeoneSerge (UTC+U[-12,12]): in opencv, why cxxdev and not dev as the output name? 05:57:42
@hexa:lossy.networkhexaand what does that mean for buildInputs?05:58:37
@hexa:lossy.networkhexaoh, opencv has no dev output05:59:19
@hexa:lossy.networkhexaand openvino has been using the wrong output all along05:59:33
@hexa:lossy.networkhexa🤦‍♂️05:59:36
@hexa:lossy.networkhexacouldn't the effectiveStdenv pattern be reduced to06:19:53
@hexa:lossy.networkhexa
+, stdenv ? if cudaSupport then cudaPackages.backendStdenv else stdenv
06:19:56
@hexa:lossy.networkhexa *
, stdenv ? if cudaSupport then cudaPackages.backendStdenv else stdenv
